Abstract: Wearable electronic devices and methods for powering wearable electronic devices are provided. A wearable electronic device includes a communication transponder, a processor, at least one storage unit and a kinetic energy system. The communication transponder wirelessly communicates with a further electronic device over a communication channel. The processor controls the communication transponder such that information is passed between the wearable electronic device and the further electronic device according to a predetermined operation mode involving interaction of the wearable and further electronic devices.

Abstract: The disclosure describes a latch retaining device to maintain the latch of a door in an inoperable position, which includes at least one body member adapted to engage and grip the door knob of the door so as to retain the door knob in its latch releasing rotated position indefinitely. The body member of the device may have first and second ends with the first end thereof adapted to frictionally engage the door adjacent the position of the door knob, whereby frictional engagement between the device and the door as well as the door knob enable the door knob to be maintained in a position to render the door latch inoperative. Alternatively, the body member may frictionally engage a door knob and exert an appropriate force thereon to maintain it in a latch releasing position. The at least one body member is secured in its frictionally engaging position by means of a cincturing strap associated with the body member.

Abstract: The invention relates to an automatic remote controlled opening device which may be used to open and close doors, windows or similar closure systems. The opening device includes a receiver to detect control signals generated at a remote location from the device. The control signals are then utilized to effect selective operation of a mechanical system coupled with the closure system for opening and closing thereof. The mechanical system enables smooth and efficient automatic opening and closing, but does not inhibit manual operation of the door or the like. Control circuitry associated with the device enables various functions to be performed for selective operation of the device. The device may also be provided with a stored energy source of power such that it can be retrofit for use with an existing closure system. Auxiliary control of the device enables opening or closing in response to an emergency situation or other circumstances.

Abstract: The utility of attachments for wrench jaws which provide gripping surfaces which will not injure highly polished surfaces to which the wrench is gripped. An attachment for wrench jaws is disclosed wherein the attachment comprises a unitary piece capable of being received over a plurality of wrench jaws and wherein the surface to be applied to the surface to be rotated by the wrench is serrated in the same fashion as the jaws of the wrench. The unitary piece further being held in position by the serrations of the wrench itself being applied against the inner surface of the attachment piece.
